  2. 1. Fracture of the distal radius - outcome, primary surgery and treatment of malunion

    Author : Antonio Abramo; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone substitute; surgery; DASH; Cerament; Distal radius fracture; Hydroxy apatite; Norian; malunion; TriMed; outcome;

    Abstract : A consensus protocol for treatment of distal radius fractures (DRF) has been developed to aid clinicians in treatment decision making. The protocol was evaluated in Paper I using a validated subjective outcome instrument, DASH in 518 consecutive patients. READ MORE

  4. 2. Total knee arthroplasty : aspects on improved fixation in the younger patient

    Author : Anders Henricson; Kjell G Nilsson; Tore Dalén; Sören Toksvig-Larsen; Umeå universitet; []
    Keywords : Surgery; Total knee arthroplasty; total knee replacement; mobile bearing; trabecular metal; hydroxy-apatite coating; Kirurgi; Orthopaedics; ortopedi;

    Abstract : The results of total knee arthroplasty are inferior in younger patients. The challenge today is therefore to develop designs and concepts that will last at least 25 years. This thesis has evaluated the fixation to bone of modern designs of knee prostheses uring RSA analysis. READ MORE

  5. 3. Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses

    Author : Yang Yu; Mattias Edén; Laurent Delevoye; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioactive glasses; Phosphosilicate glasses; Borophosphosilicate glasses; Solid-state NMR spectroscopy; Glass structure; Fourier-transform infrared spectroscopy; Hydroxyapatite; Amorphous calcium phosphate; Apatite formation; In vitro bioactivity testing; Physical Chemistry; fysikalisk kemi;

    Abstract : Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. READ MORE

  6. 4. Phosphorus speciation in Swedish agricultural clay soils : influence of fertilisation and mineralogy

    Author : Ann Kristin Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Phosphorus (P) is an important element for crop production, but build-up of excess soil P can promote P leaching and eutrophication of surface waters. To better understand the dynamics of P release from soil to waters, more knowledge is needed about sorption patterns and P speciation in agricultural soils. READ MORE

  7. 5. Composition-Structure Correlations of Bioactive Glasses Explored by Multinuclear Solid-state NMR Spectroscopy

    Author : Renny Mathew; Mattias Edén; Robert Hill; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioactive glasses; glass structure; orthophosphate distribution; solid-state NMR; dipolar interactions; dipolar recoupling; multiple-quantum spin counting; READOR; REAPDOR; fysikalisk kemi; Physical Chemistry;

    Abstract : This PhD thesis presents a study of structure-composition correlations of bioactive glasses (BGs) by employing solid-state Nuclear Magnetic Resonance (NMR) spectroscopy.Silicate-based Na2O−CaO−SiO2−P2O5 BGs are utilized clinically and are extensively investigated for bone regeneration purposes.
